ALUMINUM, You Never put in dishwasher. Stainless steel you can though unless you just don't want to take a chance on their word that U can.

I have washed my same 18/10 stainless steel pots (from two different sets by two different maufacturers) in the dishwasher for many years.  They still shine like new.  Hell would freeze over before I'd spend time at the kitchen sink washing and drying anything made of stainless steel by hand.

I never wash any nonstick pots and pans in the dishwasher, no matter what "brand" or type of nonstick coating they have.   My nonstick pans last a long time, because I try to cook and clean them precisely according to factory directions.

As for Le Crueset and other brands of enameled cast iron, I wash the big ones in the dishwasher and the smaller (5 quarts or less) ones by hand--no matter what the factory instructions say.  I've not noticed any harm that comes to the enameled cast iron by the dishwasher.

Dishwashers don't have to be set at the hottest and harshest wash settings, and I've even managed to wash crystal wine glasses and sterling silver flatware in the machine on a gentler, quick-wash  setting, although I wouldn't try doing this this very often.
